Power adapter is plugged in, laptop is on and working, but battery isn't charging above 0%

Product Name: HP Laptop 15-bs1xx
Product Number: 6BS61UA#ABA

Issue: Battery
Description:
About a month ago, I bought a new battery because my laptop said my old battery had very "low capacity", my old battery would never charge above 0% while my laptop was on or off, and if I removed my power adapter, my laptop would immediately shut down. I've used the old battery for about one and a half years.
After installing the new battery, my laptop was working perfectly fine for about a month, until a few hours ago.
I left to go do something and accidentally left my laptop on. When I came back, my laptop wouldn't turn on, so I assumed that it ran out of battery (which was the case). As it charged, I was using my laptop and noticed the battery was at 7%. Then after about 2 hours, I hovered over the battery icon and it read "100% fully charged" so I unplugged the power adapter.
However, after unplugging it, my laptop immediately switched off. Because I experienced this before, I didn't want to immediately make assumptions that my battery was broken/damaged, so I uninstalled my battery to check if there was any dust/debri or if the battery was loose, then reinstalled it.
My laptop wouldn't turn on unless I plugged in the power adapter, and when I did, I was met with the exact screen saying my battery had "low capacity", and when I signed in and checked the battery icon, it was at 0% (and it's still at 0% as I'm writing this) and having the same problems as my old battery.
Here's some other side information on how I charge my battery: I always charge it to around 90%, remove the power adapter, and plug in the power adapter again when the battery drops around 40% (takes about 2-3 hours to drain to that percentage I think). 
My laptop is currently working fine. I'm using it right now to type this message, but the power adapter is literally its life support, and I can't go anywhere with my laptop without the power adapter being plugged in. Plus, a battery that never charges above 0% obviously has some issues, and I don't want to accidentally damage my laptop.
Thanks for reading this, and have a nice day.

Hi@shirley_h12, Welcome to the HP Support Community!

I understand that you have an HP Laptop 15-bs1xx and the battery charges stuck 0% and then stops. You've done a remarkable job performing the steps. 

Did any software changes or updates happen on your laptop after which the battery stopped charging at stuck 0%?

While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

NOTE: You may skip any steps that have been performed by you already.

• Power off the laptop.
• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.
• Power ON the laptop.

Now let us uninstall the battery drivers and reinstall them. The following steps will help:

• Open the device manager. 
• Expand "Batteries". Right click on the ACPI battery drivers and select uninstall. If there are multiple entries of the ACPI battery drivers then uninstall them all.
• Close the device manager.Restart the laptop.
• The Windows operating system will reinstall the battery drivers while restarting. 

It is a good idea to download and run a BIOS update for your laptop via this link. The charger must be connected until the BIOS update is complete to avoid any power interruptions due to battery draining out. 

Post a successful BIOS update,  you may check if the battery charges fully. If not then please perform the steps as described in detail in this HP document. These steps help in testing and calibrating the battery. 

NOTE: Please skip the steps mentioned in "Test and calibrate the battery using HP Support Assistant".

I sincerely hope this fixes the issue. Keep me posted.
